An extraordinary week in the currency market has seen sterling gain against the US dollar but lose ground against the euro.

The movement has caused economists to speculate that the long period of US dollar strength is now crumbling. And now euro-sceptics who predicted the euro would roll over and die must prepare to eat their words. It has gained strength against the pound this week and many analysts in the City expect it to look even stronger soon.

So what does this mean for you? Travellers venturing to euroland this summer will see the number of euros they can buy with their pounds shrink. Prices will be dearer and the pound will not stretch as far. Anyone planning a trip may be well advised to buy euros early so you get more for your money. Conversely, it is the opposite if you plan a trip across the Atlantic this summer. Travellers to the US will get more dollars to the pound -meaning even more bargains can be had on a shopping trip to New York. It will probably make sense to leave exchanging your pounds until the last minute so you can buy more while you're away.

Shopping around to get the best deals on exchange will save you money. Look out for commission-free deals which can add an extra dollar or two on to your holiday money. Jobs & Money this week carried out a snapshot survey in an attempt to find the best deals on the high street. The Post Office and Travelex online, which both offer commission-free exchange, came out top.
